On the first day of trading after a horrendous week of losses, the Dow Jones industrial average skyrocketed up as much as 976 points and ended with a 936-point gain Monday afternoon.

As reported by CNNMoney.com, investors were betting that the worst of the credit crisis is over, following a series of global initiatives announced over the last few days.

The resulting advance was the largest ever during a session on a point basis. It was equal to an increase of 11.1 percent, the fourth-best day ever on a percentage basis.

The Standard & Poor’s 500 index added 11.7 percent, and the Nasdaq composite added 11.8 percent.
